Millwall have signed Josh Coburn on a season-long loan deal from Middlesbrough and fellow striker Mihailo Ivanovic from Serbian side FK Vojvodina.
Coburn, 21, started Boro's 5-0 EFL Cup thrashing at the hands of Stoke City in midweek but has been limited to five minutes as a substitute in the league so far this season.
He has scored 10 goals for Boro since making his debut in 2021 and also scored 10 times during a loan spell with Bristol Rovers in League One.
Ivanovic, 19, has signed a "long-term contract" for an undisclosed fee.
